Hydrodynamic/acoustic splitting approach with flow-acoustic feedback for universal subsonic noise computation
Roland Ewert, Johannes Kreuzinger
A generalized approach to decompose the compressible Navier-Stokes equations into an equivalent set of coupled equations for flow and acoustics is introduced. As a significant exte…
Efficient prediction of broadband trailing edge noise and application to porous edge treatment
Benjamin Fassmann, Christof Rautmann, Roland Ewert +1
Trailing edge noise generated by turbulent flow traveling past an edge of an airfoil is one of the most essential aeroacoustic sound generation mechanisms. It is of great interest…
Analytical reconstruction of isotropic turbulence spectra based on the Gaussian transform
Attila Wohlbrandt, Nan Hu, Sebastien Guerin +1
The Random Particle Mesh (RPM) method used to simulate turbulence-induced broadband noise in several aeroacoustic applications is extended to realise isotropic turbulence spectra.…
Overset LES with Application to a Turbulent Channel Flow
R. A. D. Akkermans, R. Ewert, N. Buchmann +2
In this contribution, we present an application of a novel perturbation approach (denoted as an Overset approach) to a generic turbulent channel flow. The derivation of the governi…
